wire usually low voltage, usually of 18awg. No rubber used, just 2 layers of cotton twisted in opposite directions.

C

Two or more stranded wires with flexible insulation for temporary use. Thermoset or Thermoplastic, Dry Use Only. Rough service wire, but not as nice looking as “PO”. Twice as thick in insulation but similar to “PO” with silk or Rayon top layer. Usually a yellow / green braided jacket, “Green and Yellow Cord”. No outer jacket to wires, just twisted single strands. Lamp Cord, 2 or more 18-10Awg. (Now is Thermoset or thermoplastic insulation with outer cotton cover.) Pendant and portable use, not hard usage in dry locations.

Lamp cord with outer layer of silk or Rayon. Wires not Twisted but Parallel. Cotton yarn wrapping round twisted strands; Insulators of rubber on top of cotton, which insulates rubber from sticking to strands making it more flexible. Cotton layer atop Rubber, with Rayon or silk jacket enclosing two wires in parallel.

POSJ

New Replacement for “PO” using a rubber jacket encasing both wires, and does not fray like fabric wires, can be washed.

Hard Service Cord with two or more stranded conductors 18 - 2 Awg. with a serving of woven cotton between the copper and the Thermoset insulation. Jute or other “fillers” are twisted together with the conductors to make a round assembly. Outer jacket of high quality rubber or modern Thermoset. For Portable or Pendant, damp locations. Extra Hard Use. Stage and Garage Use.

SA

Silicone Rubber or Silicone Asbestos, 194°F. For dry and Damp Areas. Silicone Rubber insulation with Glass or other Braided covering. (392°F. Special Applications)

‘Flexalloy is a PVC based UHMW therrmoplastic elastomer from Teknor Apex, Vinyl Division, that is billed as being “lighter, more flexible, and more resistant to extreme cold” than cable produced with conventional compounds. Coast Wire and Plastics Technology is using it to jacket a new line of cable that they manufacture, called FlexOLite Touring Cable. The Flexalloy compound is used for the inner insulation and for the outer jacket. “One big advantage of Flexalloy vinyl TPE for insulation and jacketing is that it weighs only half as much as rubber,” - Jim Crisman, VP of the Entertainment Div. Of Coast Wire (PLSN p77 Cable Construction, November 2003.

TPT

Parallel Tinsel cord. 27 Awg. 2 conductor. Thermoplastic insulation and covering. Attached to an appliance rated at not more than 50 watts and not more than 8 feet away with a special connector, for damp locations and not hard, but extremely flexible use. Not Twisted conductors.

Underground Feeder and Branch Circuit Cable, 140°F. a water proof version of NMC, rated for burial in the ground.

USE

Underground Service Entrance Cable not fire resistant but high temp. Wire 167°F. Replaces Lead shielded cable. Heavily rubber coated, with outer covering extra water resistant, can also be type “T” with thermoplastic protection.
